Describes a class activity using graph theory in the form of finding the least number of firehouses needed to serve a town as mapped by a series of points and lines connecting the points. Notes that the third graders eagerly attacked the problem, and themselves suggested that the problem could be used in grades 2-8. (RS)

Describes a science competition challenge that has students solve several hands-on physical science problems, thus reinforcing both problem-solving skills and science knowledge. (PR)

Observes that the United Kingdom's National Curriculum pressures primary teachers to change their teaching methods, but research shows equivocal results. Argues that the problem stems from the way characteristics of classroom organization have been defined in various studies. Reports on nine case studies of change in rural primary schools. (DSK)

This study examined effects of contextualized math instruction on problem-solving performance of 17 middle school remedial students and 49 average-achieving prealgebra students. Results showed that both remedial and average students receiving contextualized-problem instruction outperformed comparison groups receiving word-problem instruction.…

Reports on procedural and conceptual knowledge for solving a basic quantitative problem in chemistry by expert and novice secondary school students. Concludes that the major differences between experts and novices lay in conceptual understanding, use of a qualitative procedure, and the type of strategy used. Suggests some instructional techniques…

Asserts that becoming adept at understanding the logic of subjects, issues, and questions is a competency that, once learned, becomes a foundation for highly skilled and practical teaching and learning. Promotes the model of teaching students to seek the logic of things through the logic of science. (VWC)

Investigates science teachers' views about their use of science instructional techniques in general, and the problem-solving teaching approach in particular. Focuses on difficulties faced by science teachers in implementing the problem solving teaching approach in the science classroom. Indicates teachers' concerns about covering the science…

This study evaluated the effectiveness of teaching multiplication facts and related word problems using the concrete-representational-abstract teaching sequence and strategy instruction to three middle school students with mental retardation. Evaluation of the 21 scripted lessons given each student found only four occurrences (out of 63 lessons)…

Explores the assumption that issues-centered instruction is fine for advanced students but too difficult for low-achieving adolescents when reviewing case studies of world geography classes composed of low-achieving students. Concludes that teachers confront numerous difficulties in planning and implementing issues-centered instruction for…

Introduces the Magic in a Tube activity in which students formulate questions and practice science skills. (YDS)

Explores the effects of a Problem-based Computer-Assisted Instruction (PBCAI) on students' earth science achievement in Taiwan. One hundred and fifty-nine 10th grade students enrolled in four sections of a mandatory earth science course participated in this pretest- posttest control group experiment. A significant difference was found between the…

Discusses research on middle school science learning and instruction that suggests how generative models of scientific phenomena can be developed. The Computer as Learning Partner curriculum is introduced as a curriculum that provides a firm foundation for lifelong learning through the use of authentic questions. (SLD)

Introduces a study that identifies which learning styles are prevalent in biology majors. Uses the findings of the study to design a microbiology course. Presents activities that address the different learning styles. Uses self-assessment and portfolios for student evaluation. Includes recommendations for instructional improvement. (Contains 19…

Describes the "Reading and Writing for Critical Thinking Project" which has now sent more than 70 volunteer teacher educators into 20 countries across Central Europe and Central Asia to help teachers to try out methods that foster active learning and critical thinking. Discusses support for the project, teaching strategies introduced,…

This article argues that the reason the mathematics performance of students with mild disabilities is so limited is the mathematics. Using illustrations from subtraction, the article proposes number sense be a primary goal and that within the realm of number sense, big ideas be included among the dependent variables. (Contains references.)…
